Dimensions, shape, mass and permissible variations of hot rolled steel plates, sheets and strips Go to product viewer dialog for this item. JIS G 3193:2019
This section allows you to calculate the price per kilogram or ton. JIS G3193 uses a standard density of (or 7850 kg/m³). The formula provided is: Mass (kg/m) = Cross-sectional area (cm²) × 0.785
Enacted and overseen by the Japanese Industrial Standards Committee (JISC) under the Ministry of Economy, Trade and Industry (METI), JIS G 3193 has a long history and was most recently revised in 2025. It is available in both Japanese and English, reflecting its use as a global reference.
| Standard | Issuing Body | Scope & Key Features | | :--- | :--- | :--- | | | Japan (JISC) | Dimensional and shape tolerances for hot-rolled plates/sheets/strips; specifies tolerances in millimeters. | | ASTM A6/A6M | USA (ASTM) | General requirements for rolled structural steel bars, plates, shapes, and sheet piling. | | EN 10029 | Europe (CEN) | Tolerances on dimensions, shape, and mass for hot-rolled steel plates (3 mm ≤ t ≤ 400 mm). | | GB/T 709 | China (SAC) | Tolerances on dimensions, shape, weight, and permissible variations for hot-rolled plates/sheets/strips. | jis g3193 pdf
Tolerances vary based on the thickness and width of the material. Below is a summary of standard thickness tolerances for common dimensions: Thickness Tolerances (Typical Values) Specified Thickness (mm) Width < 1600mm Width 1600–2000mm Width 2000–2500mm Under 1.25 plus or minus 0.16 1.60 to < 2.00 plus or minus 0.19 3.15 to < 4.00 plus or minus 0.24 plus or minus 0.34 plus or minus 0.34 10.0 to < 16.0 plus or minus 0.55 plus or minus 0.65 plus or minus 0.65 Measurement Rules Mill Edges : Thickness must be measured at least from the side edge : Thickness must be measured at least from the side edge 🛠 Comparison & Compliance International Equivalent : JIS G 3193 is a modified version ( ISO 7452:2013
Generally ranges from 1.2 mm to 25.4 mm for high-accuracy hot-rolled strips, extending significantly higher for heavy structural plates.
This standard is primarily used by engineers and manufacturers to ensure that steel products meet specific physical requirements. It covers: Dimensional Tolerances Dimensions, shape, mass and permissible variations of hot

If you are currently sourcing or fabricating steel, let me know:
is the cornerstone for ensuring dimensional accuracy and quality in your steel supplies What does it cover? Dimensions & Shapes: The formula provided is: Mass (kg/m) = Cross-sectional
: Defines standard values for thickness (ranging from 1.4 mm up to over 300 mm), width (600 mm to 3048 mm), and length (1829 mm to over 12000 mm).
| Aspect | JIS G 3193 (Steel Plates & Sheets) | JIS G 3194 (Flat Bars) | | :--- | :--- | :--- | | | Plate/sheet; both length and width are large relative to thickness | Elongated flat bar; length is much greater than width | | Specified Dimensions | Thickness | Width, thickness, and length | | Maximum Width | Not specified; manufacturing capabilities determine maximum | Typically up to 500 mm |
When manufacturing or purchasing steel, perfect dimensions are mathematically impossible. JIS G3193 outlines exact acceptable variations to ensure parts fit together safely. 1. Thickness Tolerances
